The whole site is about giving money to people on Github. I'd usually agree that enforcing a certain other secondary login to sign up can be a bad thing, but for a product so tightly coupled with another service like this, I think it's okay. At least for the start.

Yes. But I think the parent comment is saying that also requires that the money is given BY people on GitHub.
Scenario: I don't have a GitHub account because I work for someone that is not doing open source work. However, my own work greatly benefits from a project I found on GitHub (a PhoneGap Library, a Python script, etc). I would like to tip the people responsible for those projects.
Quite the opposite: GitHub would love if you signed up.
You probably won't log out, and chances are you'll end up on GitHub again sometime soon. You'll discover the wonders of social coding now that you have an account, and soon enough, you're a paying customer.
I'm already on there from time to time (as a "consumer"). Likewise I am aware of the wonders of social coding... which existed before GitHub did. And all of this without a GitHub account. But, AFAIK, currently there is nothing I do on the GitHub site that would be enhanced by being logged in.
But the point is not how easy is it to sign up for a free GitHub account. The point is that it seems like an unnecessary requirement to tip someone on Gittip.
I misunderstood that ticket. It reads like you are trying to open it up so you don't need a GitHub account to get tipped. That would be great as I assume that opens up the same options for giving a tip.
